I fully understand that there is a huge difference in general 'comfortableness' between those who live in Thailand (and possibly will die there) and those who come to Thailand for short termer holidays, and long termers who come here for months at a time but then go back home for months at a time.
I'm in the group (a minority) who live in Thailand and will probably die here. Our relationship is sneaking up to 20 years now and frankly, all I want to do is live in Thailand quite happily.
Three years ago we bought a country house in Surin Province, and just this year we've bought a home here in Hua Hin.
Doing that makes me feel happily 'comfortable' (on many levels and in both lovely homes) and frankly, feeling like that should be a goal and a given for anyone in their 70's.
I admit that I spent a large amount of time ~ years in fact ~ on wrestling with the "rent or buy" question, and I'm certain that those who come to Thailand with few intentions of living here should definitely wrestle as I did, and should probably come down on the 'rent' side. Totally understandable.
